Konduktivnyj a thermal stream in islandii

The General remarks about konduktivnom a thermal stream in Iceland

G.Palmason and K.Sajmunsson

The Summary. In Iceland deep distribution of temperatures is substantially broken by influence of non-stationary factors, such, as movement of water and vulkanizm. To find out character konduktivnogo a thermal stream, careful selection of chinks is necessary for measurements of a temperature gradient. Direct data about factors of heat conductivity of the breeds opened in these chinks, do not exist, however 1,7 Vt / (м*К) it is possible to consider value as a comprehensible estimation. Superficial distribution of a thermal stream is is short considered. Reduction of a thermal stream with removal from a growth axis that corresponds to an overall picture established at oceans near to active ridges is accurately visible.

In Iceland heat is taken out on a surface as a result of three processes: heat conductivity, konvektsii waters and movings of volcanic weights. The further discussion will concern basically konduktivnogo a thermal stream. Konvektivnaja a part, i.e. Warm, allocated in geothermal areas, it is in most cases studied badly. The quantity of this heat is roughly estimated by size of an order 109 kal/with, or nearby 4000 MVt, and the basic part arrives from the high-temperature geothermal areas located in an axial zone. Heat allocation at effuzivnom vulkanizme can be deduced from speed of accumulation vulkanitov, 0,045 km3/year averaging nearby that gives nearby 6000 MVt heat.
